Sony and Panasonic seek 300GB optical disc
Sony and Panasonic have just signed a basic agreement to jointly develop an optical disc with recording capacity of at least 300GB by the end of 2015.
Both companies have previously developed products based on the Blu-ray format, leveraging the strengths of optical discs. However, both Sony and Panasonic recognised that optical discs will need to accommodate much larger volumes of storage in years to come given the expected future growth in the archive market, and responded by formulating this agreement.
Sony previously commercialised a file-based optical disc archive system in September, 2012. Based on optical disc technology that Sony cultivated for its XDCAM series of professional broadcasting products, this system houses twelve optical discs within a compact cartridge as a single, high-capacity storage solution. Each disc within the cartridge holds 25GB capacity, offering a total range of storage capacities from 300GB to 1.5TB.
In July this year, Panasonic launched its ‘LB-DM9 series’ of optical disc storage devices. This series uses a dedicated magazine of just 20.8mm thickness to house twelve 100GB optical discs. A maximum of 90 magazines can be stored, providing a total storage capacity of 180TB. In addition, Panasonic adopted a newly-developed changer system together with RAID technology to offer rapid data transfer performance of up to 216MB/s, while also ensuring high reliability by protecting data from unforeseen faults.
In recent years, there has been an increasing need for archive capabilities, not only from video production industries, such as motion pictures and broadcasting, but also from cloud data centres that handle increasingly large volumes of data following the evolution in network services.
It’s not the first time such huge amounts of storage have been promised. In 2009, General Electric hit the news with micro-holographic storage technology that suggested 500GB discs might be possible.
Going forward, Sony and Panasonic will continue to hold discussions regarding the specifications and other items relating to the development of their new standard.
